How satellite data convinced the FAA to ground all Boeing 737MAX

Yesterday, the FAA suddenly decided to ground all Boeing 737MAX.

The FAA said the decision after viewing “refined” flight data provided by the company Aireon, which uses a network of satellites to provide real-time monitoring of aircraft around the world.

At the request of the FAA and NTSB, Aireon provided the data transmitted from Flight 302 to support the accident investigation.

The data that Aireon used in its analysis comes from a system called ADS-B.

Aireon’s analysis showed that Lion Air flight 610 and Ethio­pian Airlines flight 302 shared a similar flight profile before they crashed.
